Beloved Sony A55 has fallen into a coma, leaving behind it's 3 now unsupported Lenses. Find replacement A-Mount or start new family elsewhere?

I've been using my Alpha55 since 2011, a rough shutter count brings me up to 50k. Was at the aquarium a few days ago snapping a clown fish, shutter closed... camera went black, has shown absolutely no signs of life ever since.I'm sending a lens or two into the shop for a fix anyway, so I'm going to send them the body also, who knows, if it's a cheap simple fix then I'll go that way. but without keeping my hopes up I've already started considering my options.I have a Tamron 75-300mm, A Sigma 10-20mm and a Sony 1.8 35mm Prime Lens.I've seen on the internet there are still a few new or near new A-mounts to be found... The Sony A68 looks awesome, though quite expensive (I'm just a hobby photographer).I guess my question is, Should I settle for a second hand A-Mount camera (will likely be a A57 or similar) and risk running into this problem again in perhaps another 5 (likely less) years, or take the opportunity now and make the jump to E mount?Some of those E mount cameras look very appealing with how light weight they are.. is there anything major in mirrorless I should be aware of, coming from a SLT A55?I'm aware an A mount to E mount converter is a thing, but considering the loss of Autofocus, and the price, I'm thinking the plan would be to just sell my lenses and try and score some cheap E mounts.in the community's opinion, is E mount here to stay?Have cameras come a long way in the last 7 years? for example, would the features of a modern, entry level E mount outweigh those of an 8 year old mid-range A mount?For some context, I do all sorts of holiday photos, this is mostly rich landscapes but can can sometimes mean night shots with low lighting or action shots with fast moving subjects. I don't do anything professional but still would not want to be limited by a budget camera, for reference, the A55 and before mentioned lenses were fine to work with.Thanks for your time! via /r/photography https://ift.tt/2WHI2nQ
